A stable implementation of a data-driven scale-aware mesoscale parameterization

Pavel Perezhogin, Cheng Zhang, Alistair Adcroft +2

Ocean mesoscale eddies are often poorly represented in climate models, and therefore, their effects on the large scale circulation must be parameterized. Traditional parameterizati…

Machine learning for online sea ice bias correction within global ice-ocean simulations

William Gregory, Mitchell Bushuk, Yongfei Zhang +2

In this study we perform online sea ice bias correction within a GFDL global ice-ocean model. For this, we use a convolutional neural network (CNN) which was developed in a previou…

Parameterizing Vertical Mixing Coefficients in the Ocean Surface Boundary Layer using Neural Networks

Aakash Sane, Brandon G. Reichl, Alistair Adcroft +1

Vertical mixing parameterizations in ocean models are formulated on the basis of the physical principles that govern turbulent mixing. However, many parameterizations include ad ho…

Deep learning of systematic sea ice model errors from data assimilation increments

William Gregory, Mitchell Bushuk, Alistair Adcroft +2

Data assimilation is often viewed as a framework for correcting short-term error growth in dynamical climate model forecasts. When viewed on the time scales of climate however, the…

Implementation and Evaluation of a Machine Learned Mesoscale Eddy Parameterization into a Numerical Ocean Circulation Model

Cheng Zhang, Pavel Perezhogin, Cem Gultekin +3

We address the question of how to use a machine learned parameterization in a general circulation model, and assess its performance both computationally and physically. We take one…

Effective Drift Velocity from Turbulent Transport by Vorticity

Hussein Aluie, Shikhar Rai, Hao Yin +5

We highlight the differing roles of vorticity and strain in the transport of coarse-grained scalars at length-scales larger than by smaller scale (subscale) turbulence. %sub…

Gridspec: A standard for the description of grids used in Earth System models

Venkatramani Balaji, Alistair Adcroft, Zhi Liang

The comparative analysis of output from multiple models, and against observational data analysis archives, has become a key methodology in reducing uncertainty in climate projectio…

The KPP boundary layer scheme: revisiting its formulation and benchmarking one-dimensional ocean simulations relative to LES

Luke P Van Roekel, Alistair J. Adcroft, Gokhan Danabasoglu +7

We evaluate the Community ocean Vertical Mixing (CVMix) project version of the K-profile parameterization (KPP). For this purpose, one-dimensional KPP simulations are compared acro…
